Trypanorhyncha is an order of cestodes, a type of flatworm.

Some species infect gamefish, such as sciaenids, during the parasitic worm's plerocercoid stage, and are commonly called spaghetti worm because of their appearance, approximating cooked spaghetti. Such species include Poecilancistrium caryophyllum and Pseudogrillotia pleistacantha.

gollark: If UK health authorities had actually called for stopping COVID-19 vaccine use, then yes, this would be worrying.

gollark: Because it became a political issue currently.

gollark: That still doesn't fix the data apparently being bad and open-submission.

gollark: And you shouldn't just go for the worst-case scenario (conveniently one making your preferred point best) when assuming things; you should find the most realistic one, and/or provide a range.

gollark: The US government has frequently been useless and incompetent at pandemic handling (halting the J&J vaccine and initially claiming masks didn't work are the two obvious things I can think of), but that doesn't mean that everything they say is wrong, or that belief in things that the government says is necessarily just because the government says it.
